Here are the Elves (on the right) and their human students (at left). Artanaro Nar and Who’s There work with two Hermits each. Hamfast started working with Frank first, but when Frank leaves in the second book, Hamfast ends up working with the newest Hermit, Sophie Lokisdottir. The rest of the Elves teach magic to only one person apiece.
In The Guild of Ornamental Hermits fantasy novels, these Elves have also worked with one or more of the ancestors of each of their human students, dating from the 17th century onward. These ancestors were members of the Twelve Families who helped the Elves to found the ancient mystery school, The Guild of Ornamental Hermits. Sophie Lokisdottir is the exception. Hamfast has not worked with her ancestors.
